Any resemblence to a Slurpy ends with your first slurp.  The lemonade has a kick of the rind, bitter and sweet at the same time. 

Mario's has been around since the 60's.  Other flavors include cantelope lemonade, pina colada, banana and a few more.  But the lemonade is so good, I'm probably sticking with that.

Right across the street from Al's Number 1 Italian Beef.
